Tension (bobby) pin

ABSTRACT

A spring type tension main body section in the form of a loop having one fastener arm or pin which carries a felted bobby roll with a hook at the very top and at the bottom is a hinge with a spring between the ends of the arm. The arm is hooked onto the main body section which is bent upon itself to form a depending torsion loop for receiving the hook on the end of the pin. The hook latches to the loop and locks the pin. The spring at the middle of the pin acts to tighten (pull) the hair as well as tension the springs on both sides of the pin and the springs of the body section can act to take strain off the middle spring arm or pin so it will not pull the scalp of the head.

The arm is hooked onto the main body section which is bent uponitself to form a depending torsion loop for receiving the hook on theend of the pin. The hook latches to the loop and locks the pin. Thespring at the middle of the pin acts to tighten (pull) the hair as wellas tension the springs on both sides of the pin and the springs of thebody section can act to take strain off the middle spring arm or pin soit will not pull the scalp of the head.

6 Claims, 3 Drawing Figures 1 TENSION BoBBY PlN The present inventionprovides for improved safety and freedom from danger which exists withcertain applications of conventional bobby pins, such as certain snap-onor squeeze-type, etc., bobby pins, which harm the scalp by applyingexcess tension, on the hair as a result of rolling too tightly in orderto get the desired re sult or form.

It is still another object of the present invention to provide a bobbypin which conforms with the contour of the scalp so people can get anights rest, since some people cannot sleep well with conventional bobbypins.

It is a further object of the present invention to pro vide a bobby pinfor the Negro and some foreign people whose hair is thicker, coarser,but wooly, etc., and for use where the pin is in need to be a bitsmaller and larger in various cases or requires more finger room, assome peoples hair is harder to control than others.

Other ways and means will be apparent to those skilled in the art fromthe following detailed description and claims when read in conjunctionwith the accompanying drawing, within:

FIG. 1 is an elevational view of a model of the pin as used with thebroken lines inside of the pin representing the felt bobby pin roll.

FIG. 2 is an elevational view of the pin in open position with the feltarm hook off the loop.

FIG. 3 is the middle bobby pin roll supporting arm of the pin which hasa spring section and a hinge section.

The embodied works of art of the present invention shown in FIGS. 1-3 ofthe drawing compose a tension bobby pin 16 formed of extended sectionsof wire 17 and 22, respectively, which can be heat treated in anyconventional manner to impart resilience thereto. The tension pin 16 hasa main body section 18 extending as a substantial closed loop withspring coils 19 and 19, respectively, formed between the ends thereofand straight upper arm actions 20 and 21 extending axially in oppositedirections from the ends of the coil 19. The outer ends of each of thestraight upper arm section 20, 21 extends downwardly and is bent uponitself to form a depending torsion spring loop 23. The lower side isformed of supporting arms 25 and 26 extending axially in oppositedirections from ends of the coil 19', respectively.

FIG. 3 of the drawing shows the latch section as well as the spring hookand hinge which form the pivotally mounted bobby pin roll support arm,all formed of an extending action of wire 29 which can be heat treatedin any conventional manner to impart resilience thereto. The hooksection 27 and the spring section 28 are formed by bending a section ofwire. The hinge section 24 is a conventional hinge element pivotallymounted between the ends of the main body section.

We claim:

1. A device for curling hair on the head of an individual comprising; amain body section in the form of an elongated substantially closed loopand a pin member supported by said body section for engaging said hair,said pin member having the inner end thereof pivotally secured to oneend of said loop with said pin member being pivotally movable in a planeperpendicular to the plane of said body section and having a fastenermeans formed at the outer end thereof adapted to be detachably securedto the opposite end of a said loop, and said body section having springmeans provided therein between said ends of the body section on theopposite sides of said loop whereby said body section is resilientlymovable transversely.

2. A device as in claim 1, wherein said body section is formed ofresilient metal wire and said spring means is a coil spring.

3. A device as in claim 1, wherein said pin member has spring meansprovided between the ends thereof enabling said pin member to beresiliently movable transversely.

4. A device as in claim 3, wherein said pin member is formed ofresilient metal wire and said spring means is a coil spring.

5. A device as in claim 1, wherein said pin member comprises resilientmeans for engaging said hair.

6. A device as in claim 5, wherein said resilient means is a cylindricalflexible sleeve member mounted on said pin member and extendingsubstantially the length thereof.
